During production, the liquid components are fed into the reactor body through the feed inlet. The motor drives the stirring shaft to rotate the blades, stirring and mixing the materials inside the reactor. Simultaneously, a heating or cooling jacket controls the reaction temperature. After reaching the predetermined reaction time or mixing target, the finished product is discharged from the discharge outlet at the bottom of the reactor.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0025] First embodiment: Please see Figures 1 to 4 ,in Figure 1 This is a schematic diagram of the processing equipment for producing liquid chemical additives according to the first embodiment. Figure 2 yes Figure 1 A magnified view of the local structure at point A. Figure 3 This is a schematic diagram of the internal structure of the reactor in the first embodiment.

[0026] This invention provides a processing device for the production of liquid chemical additives, comprising a reaction vessel 101 and a stirring mechanism. The stirring mechanism includes a mounting frame 102, a drive motor 103, a drive shaft 104, main stirring blades, multiple auxiliary stirring components, and multiple transmission components. Each auxiliary stirring component includes an auxiliary stirring shaft 105 and auxiliary stirring blades, and each transmission component includes a first sprocket 106, a transmission chain 107, and a second sprocket 108. This solution addresses the problem that existing stirring mechanisms in liquid chemical additive production equipment have relatively simple structures, resulting in insufficient mixing of multiple reaction components within the reaction vessel 101 and difficulty in meeting the production requirements for highly uniform products. Therefore, it is understood that the aforementioned solution can be applied to the structure of liquid chemical additive production equipment.

[0027] In this specific embodiment, the reactor 101 has a feeding port 109 at its top and a discharge port 110 at its bottom. The mounting bracket 102 is installed at the center of the top of the reactor 101, and the top of the mounting bracket 102 is equipped with a drive motor 103. The output end of the drive motor 103 is equipped with a drive shaft 104, which passes through the top of the reactor 101. The main stirring blade is located at one end of the drive shaft 104 inside the reactor 101. A plurality of auxiliary stirring components are also evenly arranged on the reactor 101, and the top of each auxiliary stirring component is mechanically driven to the drive shaft 104 through the transmission component.

[0028] In this embodiment, multiple auxiliary stirring components are evenly distributed around the circumference of the reactor 101. After the drive motor 103 starts, it drives the drive shaft 104 to rotate. The drive shaft 104 simultaneously drives the multiple auxiliary stirring components to rotate synchronously through each of the transmission components, so that the main stirring blade and each of the auxiliary stirring blades simultaneously perform stirring operations inside the reactor 101. The main stirring blade is responsible for mixing and stirring in the central area of ​​the reactor 101, and each of the auxiliary stirring blades is responsible for auxiliary stirring in the peripheral area of ​​the reactor 101. With the above structure, the mixing effect of each reaction component in the reactor 101 is better, thereby meeting the production requirements of high uniformity products.

[0029] The top end of the auxiliary stirring shaft 105 is rotatably connected to the top end of the reactor 101. The auxiliary stirring blade is provided at one end of the auxiliary stirring shaft 105 located inside the reactor 101. Each first sprocket 106 is installed at the top end of the corresponding auxiliary stirring shaft 105. A plurality of second sprockets 108 are sequentially fixedly installed at one end of the drive shaft 104 located outside the reactor 101. A transmission chain 107 is provided between each first sprocket 106 and the corresponding second sprocket 108.

[0030] In this embodiment, the plurality of second sprockets 108 on the drive shaft 104 rotate synchronously with the drive shaft 104. Each second sprocket 108 transmits power to the corresponding first sprocket 106 through the transmission chain 107. Each first sprocket 106 drives the corresponding auxiliary stirring shaft 105 to rotate, thereby realizing the simultaneous driving of the central drive shaft 104 and the plurality of peripheral auxiliary stirring shafts 105 by a single drive source, ensuring the synchronicity and consistency of the actions of each stirring component.

[0031] Secondly, the main stirring fan blade is composed of multiple main stirring blade groups 111, and the multiple main stirring blade groups 111 are fixedly installed on the drive shaft 104 from top to bottom along the axial direction of the drive shaft 104. Each of the auxiliary stirring fan blades is composed of multiple auxiliary stirring blade groups 112, and the multiple auxiliary stirring blade groups 112 are fixedly installed on the corresponding auxiliary stirring shaft 105 from top to bottom along the axial direction of the corresponding auxiliary stirring shaft 105. The auxiliary stirring blade groups 112 and the main stirring blade groups 111 are arranged alternately in the vertical direction, and each auxiliary stirring blade group 112 is located in the axial gap between two adjacent main stirring blade groups 111.

[0032] In this embodiment, when the material flows from top to bottom in the reactor 101, it passes through the alternating shearing and dispersing action of the main stirring blade group 111 and the auxiliary stirring blade group 112 in each layer, so that the material is subjected to multiple stirring treatments of equal intensity at different axial depths, avoiding uneven mixing caused by insufficient stirring at a single axial position.

[0033] Meanwhile, each of the auxiliary stirring shafts 105 is provided with two limiting rings 113 at its top end. The two limiting rings 113 are located on the upper and lower sides of the top end of the reactor 101, respectively. Each of the two limiting rings 113 on the auxiliary stirring shaft 105 is provided with an annular groove 114 facing each other. The annular groove 114 is provided with a plurality of balls 115 inside.

[0034] In this embodiment, the limiting ring 113 is used to restrict the axial movement of the auxiliary stirring shaft 105 relative to the top of the reactor 101. The two limiting rings 113 are respectively attached to the upper and lower surfaces of the top of the reactor 101. The balls 115 in the annular groove 114 are in rolling contact with the upper and lower surfaces of the top of the reactor 101, respectively, so as to reduce the frictional resistance between the auxiliary stirring shaft 105 and the top of the reactor 101 when the auxiliary stirring shaft 105 rotates, and ensure that the auxiliary stirring shaft 105 rotates smoothly.

[0035] When using the processing equipment for producing liquid chemical additives according to this embodiment, each liquid chemical additive component is first fed into the reactor 101 through the feeding port 109. Then, the drive motor 103 is started, and the drive shaft 104 drives the main stirring blades and each of the auxiliary stirring blades to rotate synchronously. The main stirring blades generate axial flow and radial discharge in the central area of ​​the reactor 101, and each of the auxiliary stirring blades generates auxiliary stirring in the peripheral area of ​​the reactor 101, so that the central material and the peripheral material form a forced convection exchange. In the vertical direction, each layer of the main stirring blade group 111 and each layer of the auxiliary stirring blade group 112 are alternately distributed, so that the material is subjected to multi-layer cross-shearing during the flow from top to bottom, avoiding the flow dead zone caused by unidirectional stirring. After the material is mixed evenly and reaches the predetermined reaction time, the finished product is discharged from the discharge port 110 at the bottom of the reactor 101.

[0036] Second embodiment: Based on the first embodiment, please refer to Figure 5 and Figure 6 , Figure 5 This is a partial structural schematic diagram of the processing equipment for producing liquid chemical additives according to the second embodiment. Figure 6 yes Figure 5 A magnified view of the local structure at point C.

[0037] The present invention provides a processing equipment for the production of liquid chemical additives, which also includes multiple protective shells.

[0038] In this specific embodiment, the top of the reactor 101 is also equipped with a plurality of protective shells via fixing feet 201, and each protective shell is respectively disposed outside one of the transmission components.

[0039] In this embodiment, the protective shell completely covers the corresponding first sprocket 106, transmission chain 107 and second sprocket 108 inside it, so as to prevent external foreign objects (such as dust, debris or accidentally splashed liquid components) from entering the transmission assembly, while avoiding the high-speed rotating first sprocket 106, transmission chain 107 and second sprocket 108 from being exposed to the outside and causing entanglement or impact injury to the operator.

[0040] Each of the protective shells consists of a first half-shell 202 and a second half-shell 203 that are interlocked with each other.

[0041] In this embodiment, the protective shell is formed by the first half-shell 202 and the second half-shell 203 being snapped together to facilitate the disassembly and maintenance of the protective shell and the repair of the internal transmission components.

[0042] When using the processing equipment for producing liquid chemical additives according to this embodiment, the protective shell prevents external foreign objects (such as dust, debris, or accidentally splashed liquid components) from entering the transmission assembly. At the same time, it prevents the high-speed rotating first sprocket 106, the transmission chain 107, and the second sprocket 108 from being exposed and causing entanglement or impact injuries to the operator. Furthermore, since the protective shell is formed by the interlocking of the first half-shell 202 and the second half-shell 203, it facilitates the disassembly and maintenance of the protective shell and the inspection of the internal transmission components.

[0043] The above description discloses only one preferred embodiment of the present invention, and should not be construed as limiting the scope of the present invention. Those skilled in the art will understand that all or part of the processes of the above embodiments can be implemented, and equivalent changes made in accordance with the claims of the present invention are still within the scope of the invention.
